As thusV illustrated, tllefinvention comprises a bodyframe having .frontandrear end-members l and2'fconnected at their lowerendsby a basemember.3, and at their tops by anarch orrspan 4," whereby a rigid body frame ispro7-25 vided forsupporting the various loperative parts. l

The instrumentalities for supporting and Vrc-, tating the barrel includea horizontal shaft dat,

the front of the machine, said shaft supported4 n in a bearing 6,andbeing drivenfrom the main 3o drive shaft 'l through'the medium of` avsprocket K chain'c'onnection 8, bevelf gearing 9, themore or lessupright shaftlland the-worm gearing li.. on the said shaft 5, wherebythe latter is dgiven a continuousrotation, for feeding the barrel byv3,5r`v

shown` in Fig. 3 of the drawings.

,The annularf-barrelisupports .1.3. I4; I5,v and .l 6- are splined onthe s haft 5, by the 'spline or'V feather il, so that these barrelsupports maybe ad-` y justedtoward and away fromr each other to ace..commodate barrels of different sizes. A toothed wheel 8.isremovablyfbolted'to,the support l5,-. f

anda-,similar toothedwheel-.IB is removably boltedY to; the; support14,*these`wheels having teeth "forengaging the Vinner surface of q tljiebarrels,

vthereby to rotate eachbarrel aboutits own axis,

which aXi s isbelow; andj parallel 1 withV the axis of the shaft l5. Aswill befseen, this method pro-j vides clearance between the undersidesof,theV barrel supports and the under sideofjthe bar(- iel, so that @mythe upper-side ofthe barrer isv t line' i in 5v Fig. 201s a' similarviewrshowtngta compietecit l in engagement with thev barrel supportingand ferent sizes. Y

In order to hold the barrel in place, with its bottom head against thecushion plate 20,;the latter being backed by springs 2 l, a doorV orcover plate 22 is hinged on the body frame at 23 andV provided on itsinner side with a rotary staple clinching plate 24,-the periphery ofwhich latter is provided withl means; for clinching the points ofthestaplesthat arerinserted through' thebottom hoop. This plate 24 'hasa stern 25 rotatably supported in the bearing 26 which is forrn'edkintegrally with the plate 22, withl af-nut V2l, to hold the stub-likeshaft against ven'd'wise dis` placement. It will be seenthat theiaxisof. the;Y stub shaft 25 is co-incidentwiththe axisY of the shaft 5, andthe staples at'this end of the barrel are clinched at the upper edgeofthe plate 24 as the latter rotates with its upper edge inengagement-with the upper walll of the barrel, but with itsloweredgesome distance above the lower side of the barrel' In'otherworda-therplate 2Q rotates in unisonjwith theibarrelsupports. The door plate 22 iscontrolled bya locking ele-Y ment 28, which engages a notch 29 in saidplate, v

or inthe bracket piece 38 secured to ,thee door or plate, saidelementbeing pivotmly supported at i-i'suppery end at 3l and having a link'connection32 with the arm 313 ofthe hand leveru 34, whereby the dooror'plate 22 `may be'manually locked or unlocked. Y

the feeding of the barrel byfmeans of-'the toothed wheels I'Sand'l;9,`it will berseen that theY presser' rollers 35-4 and 35A bearagainst the upper side of the barrel, directly over the wheels f8 and19, thereby toY keep'thek barrel staves vin firm engagement with thesewheels, to prevent slippage in the feeding motion; Therollers 35 and 3Bare mounted on the lower ends Yof racks principal object or purposeofthe rollers 35, 38, and 4G isto give 'the barrels' ajuniform anddeftinite shape, and itwill beI understood that the racks upon `'which thesekrollers are mountedV are carried in suitable bearings mounted on thebody f frame ofthe machine. Looking at Fig. 5,;it will Vbe lseen.that'the axes of the rollers 35 and 36 Y are coincident, while the axisofthe roller 48 is a little-above, but Vthese rollers all have axesYfixed against lateral displacement, about which they revolve. Pinions4l, @Land 43 engage the said racks, these pinions beingmounted inbearng'ssuitably supportedby'the bodyframe of the, machine. The saidpinions each have ani arm 44 provided with -a -collar 45 that yis*adapted to slide on the horizontal-rod or Vsupport-'46,said

rod being provided -with-i-iixe'd collars G1,- and with springs 48between saidcollars and the'slid# ving oollar's'45, and the end of ltherod 45 isV grip on the barrel, so that,` the barrel ymay then be removedfrom' thefront end of the snpporting'- structure upon whichthe barrelisV supported while; being rotated.vv w

bythe stapling machine.

Vthefstapli'ng machine to have'thehoops secured inplacerv Thislbarrelset-up comprisesl the staves 52 held in barrel form by theoutside wood hoops 53,-and 5,4 at the ends thereof. vThe bottom head 55is placed inthe barrelV and is secured in place This is done at the timethat'the wireihoops 56 arerstapled in place, and vatthe same time thatthe inside bottom hoop Or instead of the .wire hoops the barrel may havethe ordinary wooden hoops 58Y as shownrin Fig. 20 of the drawinjgsi The`three Staplers 59, 60, and 6I Vdrive 'the staple's62"A thatsecure'eitherfthe wire for the wood hoops in place, andare of'ordinaryor'any suitable construction. However, it will be Vseen that the' bottomhoop 54` issecured in" place by pairs of' staples 63, the membersof'each pair being driven: at an angle` to "each other,.and for thispurpose 'ajspecial stapling mechanism is veinployed.

' The double stapler head |62 is shown in Figs. 9 to 16 inclusive,involvesa single casing for all of the elements' thereof, so that it maybe mounted VandY operated like afsingle'` head, 'and is constructediasfollows:' Looking at Fig. 1l, 'and the other said figuresv of' thedrawings, it will: be seen that there are two staple formers 64 and B5,and two stapleY driversA 65 and 6l, and two anglesY or loopV bars 68 and69, saidfl'oopibarsbeing'pivoted at l0 andV ,'H; on the. housing l2 ofthe stapling mechanismz` VThetwo staple drivers are rigidly connected tothe head blocklS, but each staple former has a vslidingl connection withthe staplev driver .there being a locking dog 14 pivoted on the stapledriver, and normally vthe lower end of this dog engages the upper endportions 15 of the staple formers.` Springs 'l5 are provided to`yieldingly'hold* the dogs M in locking engagement'with their respectivestaple formers. rEach locking dog has a cam portion'll' for engagementwith a stationary camV 18,'when the staple drivers and the two formersmove downward in unison, thereby to vunlock the staple formers at themoment when their lower ends engage thebarrel,V

cate former and driver andV loop bars, etc., are

all Vin a single casing, as stated. Fig. 10 shows the lower'end ofthis'stapling mechanism, and shows the angles vat which the two staplesare driven, relative 'to eachother, whereby onestaple 'of veach pair 'isinserted through the' outside bottom hoopand through the inside hoop 5land clinched; on the edgeof theplate 29. while the other; staple ofVeach Apair is driven through the outside bottom hoop '5 4 and' into theedge of the head or end-wall 55'ofthebarrel. Fig. 14 showsthe Aangles atwhich-the "wires 19 and 80 are fed to thestapling mechanism, overthelower end portions of the two loop bars, and Figs.-

l 1,999,821 12 and 13 show how the feed tubes 8I, through.

which the wires are fed, co-operate at theirends with thev lower ends ofthestaple formers to cut off a length of wire, reachingl across the'faceof the lower end .of Veach stapleformentherebygto bend this cut-off;portion offthe wire over;

'drivers and thetwo staple formers andV the. twoy loop bars and theotherparts, is compact andY efficient, and with this mechanism thestaples are driven in successivepairs throughthe bottom hoop of thebarrel, in the manner explained. As shown in Fig. 5, one staple of .eachpair is driven obliquely in the inside end hoop 51, and the other isdriven in the end wall 55, so the staple heads in one row are oblique,and arestraight in line in the other row.

It will be seen that the staplers'are all mounted on a bar 82,-that isto say, the housings of the Staplers are bolted or otherwise fastenedtothis` Y bar, and the head block of each stapler, similar to the headblock 'IS, shown in Fig. ll, is connected by a link. 83 with the walkingbeam or rocker arm 84, which latter 'isV pivotedonthe horizontal shaft85 held in the supports 8S on the body frame. Each rocker arm 8d isconnected by a pitman 8l vwith an eccentric88 on the'shaft l,

whichlatter is suitably supported by the bodyy are mounted is in turnsupported on curved bracket plates 9|, which slide in guides. 32 Von thebody frame. `These. bracket plates Si are curved about the axis of thebarrel, approximately, and these bracket plates are connected by apitman 93 with the ecoentrics 94 on the shaft'l previously mentioned. Bythis means, the

stapler heads are all moved in unison, about the axis of the barrel, andthe elements are so timed that the stapler heads move at y'the time thatthestaples are actually inserted, whereby the barrel and the staplerheads are actually moving in unison, about the axis of the barrel, whilethe staples are being inserted in the barrel materials. It will be seenthaty the shaft 95 of the said feed rolls QD is carried on thetwo plates9|, and that this shaft has a ratchet wheel 9G for Vengagement with theratchet dog QJ, which latter is suitably pivoted on the housing of theguides 92, whereby the wire for the staples is fed forward each timethat the plates 9i move upwardly. In

this way the wire is fed during the back-strokel of the Staplers, so tospeak, as the staple formers and drivers are rising after the insertionof the previous staples.

Means are provided for feeding the wire hoops Y 56 as follows: The frontside of themachine is provided with three shafts 98, 99, and. |30, theshaft 99 beingY driven by-a sprocket chain llextending to a sprocket 102on theshaft of the barrel support.

Feed rolls w3k are. provided onv the shaft I 00 of afwell-known form, toengage tion l on the shaft 98, which occurs when the the wires fromwhich the-'hoopsare made, andthis shaft Iil` is driven by said sprocketchain l t l. vthrough the medium of the gears iil 'andthe clutch H35.The shaftSS is rotatable by means of ahandle'l, `and is alsoendwisemovable by thev Vbell crank llwhen the latter strikes the proies-,4

handle |03 is used to'rock thevshaft in a manner toybring` theprojection Hi8 into the path of thel bell crank IB'L'Which latter` isoperatedr bythe link IBS `pivotedon the bar 82, wherebymovementof thelatte1` operates the said bell crank to shift the shaft Q8 'endwiseVWhen this occurs, the cutters ll, of a well-known form, are operated tocut the wires,l thebarrel having been completed, and in addition theclutch lee is opened, thus automatically stopping the feeding. of the'wires for the hoops.Y The said wire feed-- ing and cutting mechanism isold and well-known,

but in this casethe wire feeding and the wire cutting devices areoperated 'advantageously from the bar 82 through the link. ll, in the;lmanner explained. W If wooden hoops are desired for the barrel, then'the ordinary hoop guides il i are movedinto alignment with the StaplersSi) and bl, and-it will be` understoodthat the` wooden hoop stripsaresimply fed into these guidesby hand. 'f 'a To changethe spacing of thestaples on the barrels, the ratio ofthe sprockets for the chain belt 8may be changed, by substituting different sprocket wheels in a mannerwhich Will be readily understood. Y Y Y In order to feed the inside hoop51 into position, the gate or door -22 at-the front lend of the machineVis provided with the opening H2 throughwhich the hoop strip for thishoop 51 can be inserted, as shown in Fig. 8 of the drawings.l Theattendant simply inserts the end portion of the hoop strip through thisopening, behind the guide l I3, on the said gate or door, and behind theguide roller IM thereon, so that the strip is pulled through andguidedinto place within the end kof the barrel as soon as the first staplesare driven in the end thereof. In this way, the said inside hoop stripis gradually drawn v into the end-of the barrel, immediately outside ofthe bottom head or end Wall, while the barrel is rotating, and-isprogressively fastened in place by the outer member of eachpf the pairsAof staples 63, these staples being clinchedY on lthe periphery of therotary plate 213 in the manner previously explained.

Means are provided for giving the wires for the wire hoops a preliminaryfeed'into position to have their-ends secured to thel barrel by thefirst staples driven, and thereafter the feed is automatic. is providedon the shaft |03, by which to rotate this shaft, after the wires rhavebeen cut and the finished barrel has been removed and another barrel hasbeen placed in position.` As soon as the fresh ends ofthe wires-,arestapled ink place,` the automaticfeeding of the wires by the rotation ofthe shaft Vlull is in synchronism with the rotation of the barrel, asthe ratio of the drive through the chain belt Allil is such that thewire feeding rolls serve to feed the wire at the same speed that the.

barrel rotates, lbut when the wiresarevag'ain cut, as previouslyexplained, this wires is then interrupted. l

In use the machine vshownand "described vis power driven, in anysuitable `or desired manner, as by'a belt on the pulley? I I6 on thedrive? shaft 'l .previously .mentioned Any suitable means,

For this purpose a crank handle l ia powerv feed ofk the therefrom. v

Thus the barrel support comprising the ele-A such as the foot treadleI1, can be employed for controlling the power and starting and stoppingthe machine at will. Y

From the foregoing it will be seen thatv ama-v T staplers areadvantageously mounted on curved bracket plates which slide in curvedguides, so that Ythe Staplers 'move on the line of a circle, the axis ofwhich is the 'axis of the barrel, and during such'feeding motion of thebarrel and action of the Staplers only the upper side of the barrel isin engagement lwith the supporting and feeding means.V The barrelset-upsare easily and conveniently placed in the machine, and theV nishedbarrels are easily and quickly removed ments I3, |'4,"|5, I6, |8,`an`dI9, and the shaft 5, is in effect barrel-shaped in form, but is of lessdiameter than any barrel that would be made on the machine, whereby saidsupport will accommodate barrels of different sizes. In each case, thebarrel is engaged only at' its upper side, so that its lower side hangsfree of the barrel support,' but the latter is entirely rotary landhasno portionsV that are stationary or fixed. The hoop 51 is notl fed intoan open end of the barrel, but to the contrary is fedv into the closedend of the barrel.

f Also, vthe'hoopA 53 may be a permanent hoop, or

it may be a temporaryhoop, depending upon the method or mannerin" whichthe barrel is made. At the rear end of the rotary barrel support, thereis a fixed plate ||8 secured to the frame of the machine, with anopening I9 therein for the shaft 5, which plate` forms an abutment forengaging the open or inner end of the barrel, as shown in Fig. 5 of thedrawings. The means for guiding or feeding in the hoop 51 are not on thebarrel support, but to the contrary are on the hinged gate 22, aspreviously explained." It is obvious, of course, that similar hoopguiding or feed- Y ing means could be placed on the plate I I8, shouldit be desired to feed an inside hoop into the open end of the barrel. ll

It will be seen that the machine shown and described is designed for the`manufacture of bilge Y barrels formed of staves assembled and held to-Agether by hoops in bilge barrel form. More broadly considered,however,it will'be seenY that many of the features Vof the machine shown anddescribed may be used on machinery for the manufacture of 'receptaclesor containers of other shapes or forms.

As a matter of special improvement, it will be observed thatvsprings'nil are `provided underf neath the shaft -35, one for eachrocker armor walking beam 84, and that set screws I2 I'are pro vided forregulatingV the tension of these springs.

'Ihe construction is such, it will be seen, that ifV the materials areof greater thickness, there will be no breakage, inasmuchas the springs|2-will permitthe armsor beams 4-to rise on the'shaft 85, when thevStaplers strike the materials, if the pitmenl have not quiteinishedtheir'upward'.

stroke. In` this Way, thestanle drivers ofthe Staplers areyieldinglybacked, so to speak, so that the staples are yieldingly driven. It willalso be seen that each rockerarm 84 has `an upper set screw |22 thatbears against 'thetop-of the" shaft 85, preferably through the mediumYof'theslidebearing shown, so that the rocker arm can be raised andlowered on the shaft, thereby to accurately adjust the normal positionthereof. The springs |20, it will be seen, are preferably supported byhanger brackets |23, which are removablysecured to the under side of therockerarms bythe screws |24, whereby the rocker arms can be readilylifted from the transverse overhead shaft 85, by simply removing thesebolts, and by disconnecting the pitmen 81 either at their upper or lowerends. Thus in effect a yielding fulcrum is provided for each rocker arm,under the fixed axis formed by the shaft 85, so' that the rocker armitself can give and prevent breakage of the machinery, and preventcrushing of the-materials, if the latter are a little thicker thananticipated. .The effect, of course, is to yieldingly drive the staples,forin effect the transmission of power through the actuatinginstrumentalities to the stapler is yielding instead ofV positive andnon-yieldingbut the springs |20, of course, are of sufficient stiffnessor tension to insure suilicientffulcrum or resistance to properly drivethe staples.V

In connection with the relative arrangement of the staples 63, thosethat enter the head 55 being driven in a straight line, with their headsparallel with said line, while those that are driven in the inside hoop51 being driven obliquely to a straight line, it will be seen, asindicated in Figs. 9 130.16 inclusive, that the said oblique staples areformed by the Vstaple former 65,'whi1e the said other staples thataredriven in the barrel head are formed by the staple former 84,' andfor this purpose it will -be seen that the former |55 is disposedangularly in relation to the staple former 54, in the manner shown moreclearly in Fig. l ofthe drawings. It will'alsobe'seen that the former 64is housed in themain body portion of the casing 12 while the former 65is housed in the removable section |63 of said casing." The body 12has'a bracket |64 whichis supported on the transverse bar`82 of themachine, previously mentioned, as are the otherstaplers, and in this waythe Astapler |62 is a multiple staple former and driver, and is adaptedto drive two staples at a time, close together, but with the head of onestaple of eachpair disposed at an angle to the head ofthe other pair, asshown and described.v

Thus the heads of thestaplesY 63 that are driven into the hoop 51 narecrosswise of the 4grain of the hoop 54, while the staples that aredriven into the head 55 are not crosswise of the grain of thehoop 54,butrare crosswise of the grain of the staves 52,' andthe pairs ofstaples thus inserted are effective vto provide a' strong barrelheadbottom'construction, and the machine that is shown and described iscapable of eicient and accurate and relatively high'speed production inthe-manufacture of barrels of the kind shown and described.

Furthermore, it will be seen that the two staple fcrmers E4 and 55 arepreferably merged into one integral memberl 65, so to speak, whichlatter is-wedge-shaped in horizontal cross-section, as shownlin Fig. 15of the drawings. In addition, as shownin Fig. 14 of the drawings, itwill be seen thatthe twovv converging wires1|| and 80, of whichY thestaples are formed, have their converging ends received' in a recess |66suitably formed 'in a removable member l'lthat is pro-V vided to extendvertically at one rside of -Ythve stapling mechanism, andi which isremovable from the housing. Inthis way, a single verticallyreciprocating member IE5, .acting in effect as two staple formera servesto simultaneously cut offl two portions of wire, andA to bend theportions into staples of the rdesired width and length, and the twostaples are then driven in the manner shown and described. l
